I moved to the US last year and work a regular full-time job. I haven't had to file taxes before, since I only started work in May. I'm about to launch my first 'weekend project' to potentially involve some advertising and Amazon-affiliate revenue. I'm not really clear on what I should be doing and what is necessary with regards to tax, registering as a business, etc.
Can anybody recommend any good resources for information to help me avoid situations like this chap has got himself into?
Get a cheap tax-accountant. It seriously can take years to really come up to speed on our tax system. It's not so complex that a somewhat trained professional can't answer all of your questions, and ask you some good ones in a short session, but it's relatively easy to miss something doing your own research. Do as I say, not as I do, of course!
